Broken links are still being repaired. Keep the input rolling.

Finally: My site aims are fairly complete. However there is still room for some more calculators, so give me some hints as to what could be of use to those genuine engineers out there.

Work has startedon microstrip stepped line filters to fulfill a request.

The Antenna area has been expanded to include the dielectric format. At the moment just the design, later the radiation patterns will be added.

Our companion site LongleyRice is now more complete. Better explaining of the ITM and some new documentation.
